Aside from FEMA's formaldehyde traps post-hurricane Katrina, there's been plenty of examples of trailers -- remodelled or otherwise -- now featuring more high-end green design. With the emphasis on lightweight, flat pack construction, California-based Bellomo Architects' House Arc is another such stellar example of compact, off-grid living, but with disaster-resistance in mind. The first prototype is seen on this video being built in Hawaii:

Since it is designed to withstand tropical storms, it is intended also as an affordable, long-term replacement for structurally unsound housing, suitable for the aftermath of natural disasters like Hurricane Katrina and Haiti's 2010 earthquake (though the glossy rendering looks like it's more of a poolside resort).

Modelled after the compact and curvaceous form of the old-school trailer, House Arc's structure consists of a steel rib tube framework, clad with polycarbonate sheeting and wood, weighing a total of only 3000 pounds. The idea is to have a house that is easy and quick to assemble on-site.

There's also a rainwater collection system, photovoltaics on the roof and more:

Large windows provide natural light, maintain views, and funnel in ocean breezes to cool the interior while the shading trellis limits heat infiltration. The raised structure allows air to flow underneath for cooling, functions with the site terrain, and maintains the permeability of the site.

Though one could also see it as an extra work-pod out back in the yard, t's the hope of the architects that this modular housing system will catch on with relief organizations for rebuilding situations -- definitely a better option than flimsy, makeshift tents or toxic trailers.
